its on-off state, which will be reported to the KNX bus through the
corresponding status object, if enabled.
Shutter Channel: when the button is pressed, the device will act over the
output according to the length of the button press and to the current state.
➢ A long press makes the shutter start moving (upwards or downwards,
depending on the button being pressed). The LED will light in green until
the end of the motion. If the button gets pressed being the shutter already
at the top or bottom positions, nothing will happen (the LED will not light).
➢ A short press will make the shutter drive stop (if in motion), as it normally
does when a step/stop order is received from the KNX bus. In case of not
being the shutter in motion, pressing the button does not cause any action,
unless slats/lamellas have been parameterized – in such case, a step
movement (up/down, depending on the button pressed) will take place.
The status objects will be sent to the bus when corresponding.
Fan Coil module: the behaviour will depend on whether a fan-labelled or
a valve-labelled button is pressed:
➢ Fan: for this type of buttons, it must be taken into account that there are
two types of control for the fan speed:
• Switching control: a short or long press will switch the relays to set the
selected speed, unless it matches the current speed – in such case all
the relays will be opened (speed 0). The associated LEDs will indicate
the state of the fan speed control relays (on = relay closed; off = relay
open).
• Accumulation control: a short or long press switch to the selected
speed, closing the relay associated with that speed, and also the relays
assigned to the lower speeds, unless it matches the current speed – in
such case all the relays will be opened (speed 0). The associated LEDs
will indicate the state of the fan speed control relays (on = relay closed;
off = relay open).
Note: the behaviour of the relays will depend on the parameterisation, i.e.,
on the number of fan speeds, and on the delay between switches.
